Shrub Rose Plant Named &#39;WEKYOOPEDKO&#39;

ABSTRACT

A new variety of Shrub rose suitable for garden decoration, having flowers of red with lighter reverse coloration with a white ‘eyezone’.

CLASSIFICATION

The present invention relates to a new Rosa hybrida plant.

VARIETY DENOMINATION

The new plant has the varietal denomination ‘WEKyoopedko’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Shrub Rose. Ithas as its seed parent the variety known as ‘WEKiscorou’ (not patented)and as its pollen parent the variety known as ‘RADtko’ (U.S. Plant Pat.No. 16,202).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combinations of characteristics: its high degree ofresistance to black spot, powdery mildew, downy mildew and rust, itsexcellent color stability throughout the life of the flower and itsrough peduncle with many stipitate glands and some small prickles. Theplant has an upright bushy growing habit, suitable for outdoor gardendecoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Pomona, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘WEKyoopedko’ maybe asexually propagated by cuttings, budding and grafting. The buddingand grafting successfully occurred on the plant/rootstock Rosa hybridacv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘WEKiscorou’ bythe following combination of characteristics: whereas ‘WEKyoopedko’bears flowers of red with lighter reverse coloration with a white‘eyezone’, ‘WEKiscorou’ bears flowers of scarlet coloration with a whitereverse. The new variety has an upright bushy medium height growinghabit (about 110 to about 142 cm. in height), whereas the seed parenthas a compact rounded significantly shorter growing habit (about 30 toabout 45 cm. in height).

The new variety may be distinguished from its pollen parent, ‘RADtko’ bythe following combination of characteristics: whereas ‘WEKyoopedko’bears flowers of red with lighter reverse coloration with a white‘eyezone’, ‘RADtko’ bears flowers of red coloration. The new variety hasan upright bushy medium height growing habit (about 110 to about 142 cm.in height), whereas the pollen parent has a rounded bushy significantlyshorter growing habit (about 90 to about 120 cm. in height).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is thepollen parent ‘RADtko’ (U.S. Plant Pat. No. 16,202).

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. The branches used for the photograph came from 3 to 4year-old rose plants of the new variety grown outdoors in Wasco, Calif.in the month of October. Throughout this specification, color referencesand/or values are based upon the Colour Chart of The Royal HorticulturalSociety (1966) except where common terms of color definition areemployed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Wasco, Calif. in the month of October.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

-   Flower: The new variety sometimes bears its flowers singly, usually    in clusters of two to four per stem. Flowers may be borne in regular    rounded clusters on strong somewhat short to medium length stems    (about 18 to about 65 cm.). Outdoors, the plant blooms abundantly    and nearly continuously during the growing season. The flowers have    a slight tea fragrance.-   Bud: The peduncle is about 2.1 to about 5.8 cm. in length, of    moderately heavy caliper (about 0.2 to about 0.3 cm. in diameter),    and usually erect. It is rough, with many stipitate glands and some    small prickles. Peduncle color is between 144A and 146C often    heavily suffused, especially on the side exposed to the sun, with    between 187B and 187A. Before the calyx breaks, the bud is about 0.8    to about 1.5 cm. in diameter at the widest point, about 1.4 to about    1.8 cm. in length, and pointed to somewhat ovoid in shape. The    surface of the bud bears between 6 to 12 foliaceous appendages and    some stipitate glands, usually with slender moderately cut    foliaceous parts extending beyond the tip of the bud about ½ or more    of its length. Bud color is between 137C and 146C often heavily    suffused, especially on the side exposed to the sun, with between    187A and 187B. The sepals are about 2.0 to about 2.7 cm. in length    and about 0.6 to about 0.8 cm. in width at the widest point. The    outer surface color of the sepal is between 137C and 146C often    heavily suffused, especially on the side exposed to the sun, with    between 187A and 187B. The outer surface of the sepal is somewhat    rough and bears between 0 to 5 foliaceous appendages with some    stipitate glands. The inner surface color of the sepal is near 146C    broadly bordered by near 137B. After the sepals open, the inner    surface color is often moderately suffused, especially on the area    exposed to the sun, with between 187A and 187B. The inner surface of    the sepal is covered with fine wooly tomentum; sepal margins are    lined with some stipitate glands and many hairs. The receptacle of    the flower is of medium length (about 0.5 to about 0.7 cm.) and    average in caliper (about 0.6 to about 0.8 cm. in diameter). The    receptacle is urn-shaped in form. Its surface is smooth with    moderately thick fleshy walls. The receptacle color is between 144A    and 146C. As the petals open (after the calyx breaks), the bud is    about 1.5 to about 1.9 cm. in diameter at the widest point, about    1.9 to about 2.3 cm. in length, and ovoid to somewhat pointed in    form. The color of the under surfaces of the newly opened petals is    between 53A and 53B. At the point where the petal attaches, there is    a large zone of between 1C and 154C. The color of the upper surfaces    of the newly opened petals is between 187A and 187B. At the point    where the petal attaches, there is a large zone of between 1C and    154C.-   Bloom: When fully open, the bloom ranges from about 5.6 to about    8.9 cm. in diameter. Petalage is double with about 15 to 24 petals    and about 2 to 6 petaloids irregularly arranged. When partially    open, the bloom form is high centered to somewhat cupped, and the    petals are moderately tightly spiraled to somewhat cupped with petal    edges somewhat reflexed outward. When fully open, the bloom form is    more cupped, and the petals are loosely cupped to somewhat undulated    with petal edges moderately reflexed outward.-   Petals: The substance of the petals is heavy and of moderately thick    thickness, with upper surfaces moderately satiny to somewhat velvety    and under surfaces slightly shiny. The petals are about 2.8 to about    4.3 cm. in length and about 2.4 to about 4.4 cm. in width at the    widest point. Petal margins are entire. The outer petals are    somewhat obovate to nearly round in shape with rounded apices. The    inner petals are moderately obovate in shape with rounded apices.    Petaloids are about 1.0 to about 3.7 cm. in length and about 0.5 to    about 2.4 cm. in width at the widest point. Petaloids are    irregularly shaped moderately oblanceolate to somewhat obovate with    rounded apices.-   Newly opened flower: The under surface color of the outer,    intermediate and inner petals is between 155A and 155B often    moderately to heavily suffused with between 53B and 53C. At the    point where the petal attaches, there is a large zone of between    155A and 155B. The upper surface color of the outer, intermediate    and inner petals is between 53B and 45B. At the point where the    petal attaches, there is a large zone of between 2D and 1D. The    under and upper surface colors of the petaloids are similar in    coloration to the upper and under surfaces of the intermediate and    inner petals. The general tonality of the newly opened flower is    between 53B and 45B.-   Three-day-old flower: The under surface color of the outer,    intermediate and inner petals is between 155A and 155B often    moderately to heavily suffused with between 60B and 53C. At the    point where the petal attaches, there is a large zone of between    155A and 155B. The upper surface color of the outer, intermediate    and inner petals is between 53B and 45B. At the point where the    petal attaches, there is a large zone of between 155A and 4D. The    under and upper surface colors of the petaloids are similar in    coloration to the upper and under surfaces of the intermediate and    inner petals. The general tonality of the three-day-old flower is    between 53B and 45B. On the spent bloom, the petals usually drop off    cleanly. In October in Wasco, Calif., blooms on the bush growing    outdoors generally last about four to five days. Cut roses from    plants grown outdoors and kept at normal indoor living temperatures    generally last about four to five days.-   Male reproductive organs: Stamens are many in number (average    about 150) and are arranged regularly about the pistils; a few are    mixed with petaloids. The filaments are of somewhat short to medium    length (about 0.5 to about 1.2 cm.) most with anthers. Filaments are    between 154D and 1D in color. The anthers are moderately small for    the class and all open approximately at the same time. Anther color    when immature is near 22A on the external part and near 78D on the    internal part. Anther color at maturity is near 165B on the external    part and near 200A on the internal part. Pollen is moderate and    between 18C and 19C in color.-   Female reproductive organs: Pistils vary in number (average about    75). The styles are moderately even, average in length (about 0.4 to    about 0.7 cm.), somewhat thin to average in caliper, and loosely    bunched to somewhat separated. Stigma color is near 11A. Style color    is between 1C and 154C usually moderately suffused with between 53B    and 53C. Ovaries are usually all enclosed in the calyx. Hips are of    somewhat short length (about 1.2 to about 1.5 cm.), rounded in form    with a flat top, and between 28A and 30C in color when ripe. The hip    surface is smooth with thick fleshy walls. The sepals are moderately    permanent and usually straight in shape. The seeds are irregularly    rounded, smooth in texture, approximately 10 to about 14 per hip,    about 0.4 to about 0.6 cm. in diameter at the widest point and    between 164A and 165B in color.-   Foliage: The compound leaves are usually comprised of three to seven    leaflets and are borne abundantly. The five-leaflet leaves are about    9.6 to about 14.6 cm. in length and about 7.6 to about 11.6 cm. in    width at the widest point, moderately leathery to somewhat crisp in    texture, and glossy in finish on the upper side and matte in finish    on the underside. The leaves have a pinnate venation pattern. The    terminal leaflets are about 3.9 to about 7.1 cm. in length and about    3.1 to about 4.3 cm. in width at the widest point, shaped moderately    ovate to somewhat oval with acute to slightly acuminate apices and    rounded to somewhat acute bases. Their margins are usually simply    serrate. The upper surface color of the mature leaf is between 139A    and 137A. The under surface color of the mature leaf is between 147B    and 146A. The under and upper colors of the leaf veins on the mature    leaf are similar in coloration to the upper and under surfaces    colors of the mature leaf. The upper surface color of the young leaf    is between 137A and 146A, often heavily suffused with between 187A    and 187B. The under surface color of the young leaf is between 138B    and 146A, often heavily suffused with between 187B and 187A. The    under and upper colors of the leaf veins on the young leaf are    similar in coloration to the upper and under surfaces colors of the    young leaf. The rachis is average in caliper and rough. The upper    side is deeply grooved with few hairs and stipitate glands on the    edges of the grooves. The under side of the rachis is rough with few    stipitate glands and small prickles. The rachis color is near 146D    on the under side and near 137C on the upper side often heavily    suffused on the young leaves with between 187B and 187A. The    stipules are about 1.3 to about 1.9 cm. in length and moderately    wide (about 0.5 to about 0.8 cm.) with moderately long straight    points that usually turn out at an angle of more than 45 degrees.    The under and upper surface color of the stipule is between 137A and    137B. The petiole is average in caliper and rough. The upper side is    deeply grooved with few hairs and stipitate glands on the edges of    the grooves. The under side of the petiole is rough with few    stipitate glands and small prickles. The petiole is about 0.8 to    about 1.6 cm. in length and about 0.1 to about 0.2 cm in width at    the widest point. The petiole color is near 146D on the underside    and near 137C on the upper side often heavily suffused on the young    leaves with between 187B and 187A. The plant displays a high degree    of resistance to black spot, powdery mildew, downy mildew and rust    as compared to other commercial varieties grown under comparable    conditions in Wasco, Calif. The plant's winter hardiness and    drought/heat tolerance are yet to be determined.-   Growth: The plant has an upright bushy medium height growing habit    (about 110 to about 142 cm. in height and about 108 to about 122 cm.    spread at the widest point), with full branching. It displays    moderately vigorous growth and the canes are of medium to somewhat    heavy caliper for the class (about 1.8 to about 3.2 cm. in diameter    at the widest point). The color of the major stems is between 146A    and 146B. They bear many large prickles that are about 0.6 to about    1.2 cm. in length. The large prickles are angled slightly downward    with a medium length moderately narrow oval base; prickle color is    between 177B and 177C. The major stem bears few small prickles of    similar shape and coloration. The color of the branches is between    137C and 146B sometimes lightly suffused with between 187A and 187B.    They bear many large prickles which are of similar size and shape to    the large prickles on the major stems; prickle color is between 152D    and 152C often moderately suffused with between 187C and 187D. The    branches bear few small prickles of similar shape and coloration.    The color of the new shoots is between 144A and 146C often heavily    suffused with between 187B and 187A. They bear many large prickles    which are of similar size and shape to the large prickles on the    major stems; prickle color is between 152D and 152C often heavily    suffused with between 187B and 187C. The shoots bear few small    prickles of similar shape and coloration.
